redhat8安装yum命令

只是想在nexus提供的docker中安装一些软件，但是没想到居然是个白板系统，只能通过npm安装软件。。。

1.确认系统版本

uname -a
# Linux sonatype-nexus31 4.4.180+ #42661 SMP Fri Apr 1 15:33:06 CST 2022 x86_64 x86_64 x86_64 GNU/Linux

# 红帽专属查询
cat /etc/redhat-release
# Red Hat Enterprise Linux release 8.7 (Ootpa)

2.安装

问题主要来源于rpm的包不太好找，可以按需安装，如果是和我一样的白板系统，可以直接安装以下包

# yum
rpm -ivh --nodeps https://mirrors.aliyun.com/centos/8.5.2111/BaseOS/x86_64/os/Packages/yum-4.7.0-4.el8.noarch.rpm
rpm -ivh --nodeps https://mirrors.aliyun.com/centos/8.5.2111/BaseOS/x86_64/os/Packages/yum-utils-4.0.21-3.el8.noarch.rpm

对于python模块，也可以使用pip对其进行安装
先找到python 通过yum找到对应的python 因为没有配置python软链，所以需要此步骤

# 查找python路径（如果执行yum还有反应的话）
vi /usr/bin/yum
#!/usr/libexec/platform-python
# 使用python中的pip进行安装
/usr/libexec/platform-python -m pip install gpg

扩展-yum源更换

因为红帽默认yum也是需要收费的，所以还需要切换为阿里云，可以参考此文章进行后续处理
RedHat-8.0配置yum仓库（在线安装）

ps：

如果需要安装包，也可以直接下载包使用下载地址

也可以自己去阿里云下载，因为过一段时间可能会被清除，所以需要自己去按目录进行查找
